How to reduce WSUS disk usage?

  • 772

My WSUS installation is now using 100 Gb of disk.

Is there a way to reduce this usage? How can I, say, delete updates included in Service Packs?

  1. You can go to Options > Server Cleanup Wizard, in the WSUS window, and clean up unused updates and update revisions, computers not contacting the server, uneeded update files, expired updates, and superseded updates. I do this approx. once a week, sometimes a little less frequently.

  2. I have found another quite effective approach.

    Go All Updates folder, and set:

    • Approved on Approval field
    • Any on status field

    Then right click on column titles and check Supersencence. A new column 2 will appear. Use it to sort all your approved items.

    Select all superseded items (they are grouped by 2 different icons), and decline them.

    Then go in Options->Server cleanup wizard and set only Unneeded update files

    Run it.

    NOTE: This 'brutal' approach saved a choking server by reducing the disk usage (about 50%).
